There’s a handful of AGD logo rail-asa on eBay. Some of them are priced kinda crazy. Just FYI-
New? I can’t image there have been new AGD logo backbottle ASAs for like a decade. -
Oh I see, the ones on the site don't have the logo. I just want an AGD ASA so I know it'll fit on the rail without hassle and I figured I could get one cheaper than they are new -
Just be sure you’re buying a backbottle or “rail” ASA. They are different screw size and spacing. AGD made logo ASA’s in both so you have to be careful.
Bottom line ASA are industry standard and will have a counterbored #10 smooth through hole spaced .750” running all the way through.
Back bottle ASA were (as far as I know) only ever used on classic style AGD rails. They are blind threaded 1/4-20 at .600 spacing and use the same Low 1/4-20 SHCS that the foregrip uses.
They are not interchangeable or modifiable to be interchangeable. If you see a pic from only one angle and it’s a threaded hole, it’s back bottle. If it’s smooth through hole and/or has a counterbore it’s a bottom line ASA.
